I have attached a diff of build logs with make-3.82 and make-4.0.

The main "differences" are that make-3 uses a ` in its output whereas
make-4 uses a '.  Make-4 also does not print entering/leaving notices
when it does nothing in that directory.  I have filtered most of these
out, but you will see examples of the latter in the attached output.

The first difference is a rebuilding of C-translit.h.  I believe that
this should not happen...

The second real differences involves  I have no idea what
this is, so someone else will need to comment on that.

Finally, there are a couple of small differences at the end where gcc is
called.  I build glibc with "build-programs=no" first, then add
hardening cflags to build the binaries.  It looks like make-3 is doing
some unnecessary work in the second make call that make-4 is not doing.
